Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figures 1-11 One embodiment of the present invention is: a multi-environment tire anti-skid performance testing device for new energy vehicles, including a device base 1, a buffer 2 is fixedly connected to the top of the device base 1, a track 3 is fixedly connected to the top of the device base 1, a fixing mechanism 4 is slidably installed on the track 3, and the fixing mechanism 4 includes: a mounting seat 1 401, a support column 402, a rubber block 403, a mounting seat 2 404, a rotating shaft 405, a threaded shaft 406, a top block 407, a fixing flange 408, and a mounting shaft 409. The mounting seat 1 401 is slidably connected to the top of the track 3, the support column 402 is slidably connected to the top of the track 3, the rubber block 403 is fixedly connected to the mounting seat 1 401 and the front of the support column 402, the mounting seat 2 404 is slidably connected to the inner wall of the support column 402, and the bottom of the mounting seat 2 404 is connected to the support column 40 through an electric telescopic rod. 2 is internally connected, the rotating shaft 405 is rotatably connected to the inner wall of the second mounting seat 404 through an internal motor, the threaded shaft 406 is fixedly connected to the axis center of the rotating shaft 405, the top block 407 is threadedly connected to the circumferential surface of the threaded shaft 406, the fixing flange 408 is slidably connected to the circumferential surface of the threaded shaft 406, and one end of the threaded shaft 406 slidably connected to the fixing flange 408 is not provided with a thread, the mounting shaft 409 is rotatably connected to the inner wall of the first mounting seat 401 and is driven by an external motor, the tire 6 is rotatably connected to the fixing mechanism 4, and a heating mechanism 5 is provided inside the fixing mechanism 4. The top of the device base 1 is fixedly connected to the lifting mechanism 7, and the top of the device base 1 is fixedly connected to the connecting seat 8. The end of the top block 407 away from the mounting shaft 409 is inserted into the inner wall of the second mounting seat 404, and a sensor is provided inside the buffer 2 to record the numerical value after the impact.

[0016] Working principle: Before the device is put into operation, the tire 6 is assembled to the installation position of the installation shaft 409. At this time, the second mounting seat 404 is lifted up by the electric telescopic rod inside the support column 402. The second mounting seat 404 is lifted up to drive the rotating shaft 405 and its attached components, the threaded shaft 406, the top block 407 and the fixed flange 408 to rise to a fixed position. Then the rotating shaft 405 is driven by the internal motor of the second mounting seat 404. The rotation of the rotating shaft 405 drives the threaded shaft 406 to rotate. The rotation of the threaded shaft 406 drives the top block 407 to rotate through the surface thread. Since the top block 407 is inserted into the inner wall of the second mounting seat 404 and is constrained, it cannot rotate and can only move along the direction of the threaded shaft 406. The top block 407 moves to push the fixed flange 4 08 moves. When the fixing flange 408 is buckled into the mounting shaft 409, the top block 407 completes the entire stroke and moves out from the inside of the mounting seat 2 404. The motor inside the mounting seat 2 404 stops. Due to the self-locking nature of the thread, the fixing flange 408 firmly fixes the tire 6 on the mounting shaft 409 and prepares for testing. When the device completes the test, a special tool is used to fix the top block 407. The motor is reversed and the mounting seat 2 404 is lowered to remove the tire 6. The motor can set a torque limit and automatically stop when encountering resistance to protect the equipment from accidental damage. This design can also avoid errors during manual tightening operations, which can lead to the risk of falling off due to over-tight assembly that is difficult to disassemble and over-loose assembly, thereby reducing labor costs and improving operating efficiency.

[0018] The lifting mechanism 7 includes: a test plate 701, a support frame 702, a limiting column 703, and a hydraulic telescopic rod 704. The limiting column 703 is fixedly connected to the top of the device base 1, the support frame 702 is slidably connected to the inner wall of the limiting column 703, the hydraulic telescopic rod 704 is fixedly connected to the top of the device base 1, the test plate 701 is slidably connected to the top of the support frame 702, and the top of the test plate 701 is symmetrically provided with guide rails. A pressure sensor group is provided at one end of the test plate 701 close to the tire 6 for detecting the numerical value of the anti-skid performance of the tire 6. The lifting mechanism 7 also includes: a push plate 705, a water outlet 706, a water combing plate 707 ... combing plate 707, a water outlet 706, a water combing plate 707, a water outlet 706, a water combing plate 707, a water outlet 706, a water combing plate 707, a water outlet 706, a water combing plate 707, a water outlet 706, a water combing plate 707, a water outlet 706, a water combing plate 707, a water The gate plate 708, the push rod 709, and the water outlet 706 are arranged on the top of the test plate 701 and connected to the external water source. The push rod 709 is slidably connected to the top guide rail of the test plate 701. The push plate 705 is fixedly connected to one end of the push rod 709. The sluice gate plate 708 is slidably connected to the other end of the push rod 709. The combing plate 707 is slidably connected to the inner wall of the test plate 701 and is driven by an external servo electric cylinder. The bottom of the support frame 702 is fixedly connected to the protruding end of the hydraulic telescopic rod 704. The sluice gate plate 708 is rotatably connected to the inner wall of the test plate 701. When the sluice gate plate 708 is in the initial position, the bottom of the sluice gate plate 708 is in contact with the test plate 701 and sealed.

[0019] Working principle: To control the temperature variable, the tire 6 needs to be heated to the set temperature before testing. First, the heating rod 502 starts to heat up, and then the mounting shaft 409 is driven by the internal motor of the mounting seat 401 to rotate slowly. The rotation of the mounting shaft 409 drives the lever 506 to rotate, and the lever 506 rotates and contacts the connecting rod 504 and pushes the connecting rod 504 to move. The movement of the connecting rod 504 drives the slider 503 to move along the arc-shaped guide groove on the surface of the shield 501 and stretches the spring 505. The movement of the slider 503 drives the heating rod 502 to move. The heat can be dispersed to a larger area through the movement of the heating rod 502, reducing local high temperature. Risk, when the lever 506 moves to the position of the wedge block 507, continue to rotate the inclined surface of the wedge block 507 to lift the lever 506, and the lever 506 lifts the connecting rod 504, which loses its constraint. The slider 503 is pulled back by the restoring force of the spring 505. When the lever 506 passes over the wedge block 507, it is reset by the internal torsion spring. As the mounting shaft 409 rotates, it contacts and pushes the connecting rod 504 again, thus circulating, further improving the heating efficiency and making it easier to achieve uniform distribution of surface temperature. It is suitable for tires 6 with complex tread patterns on the surface. It can reduce energy waste by evenly distributing heat, and is also suitable for long-term continuous operation.

[0020] In order to realize the test under different environments, the test slope can be adjusted, the hydraulic telescopic rod 704 located at the front of the device is lowered, and the hydraulic telescopic rod 704 located at the rear of the device is raised. The cooperation between the front and rear groups of hydraulic telescopic rods 704 can make the support frame 702 freely adjustable within a certain angle range. When the front and rear groups of hydraulic telescopic rods 704 are raised at the same time, the influence of different loads on the test results can be simulated. After the slope, weight and various parameters are set, the installation shaft 409 is driven to rotate by an external motor. The rotation of the installation shaft 409 drives the tire 6 to rotate. The rotation of the tire 6 and the friction with the test plate 701 drive the entire fixing mechanism 4 to wrap In summary: Mounting base 1 401, support column 402, rubber block 403, mounting base 2 404, rotating shaft 405, threaded shaft 406, top block 407, fixing flange 408, and mounting shaft 409 move forward. The sensor at the end of the test plate 701 near the tire 6 reads the value and completes the record. When the tire 6 reaches the set position of the test plate 701, the caliper locks, causing the tire 6 to stop rotating. Due to inertia and tire 6 performance, mounting base 1 401 may continue to move. The movement of mounting base 1 401 drives rubber block 403 to move until it strikes bumper 2, stopping mounting base 1 401. The sensor inside bumper 2 reads the value and completes the record. When testing the wet-weather performance of tire 6, water outlet 706 is opened and water begins to accumulate on the end of test plate 701 away from tire 6. Because water is sealed in sluice gate 708 and prevented from flowing out, the tire 6 contacts and pushes push plate 705 during testing. This movement of push plate 705 drives push rod 709, which in turn rotates sluice gate 708, causing water to flow out. The water then passes through combing plate 707, whose external servo cylinder drives it back and forth, ensuring a smooth and even flow toward test plate 701. As the number of tests increases, more water accumulates on test plate 701, recording the performance of tire 6 under various humidity conditions. This design eliminates the increased labor costs associated with manual water addition and reduces errors that can reduce data accuracy.

There are numerous methods and approaches for implementing this technical solution. The foregoing is merely a preferred embodiment of the present invention.
